context_page_description: Automatic lubrication refers to a lubrication system on a two-stroke engine, in which the oil is automatically mixed with fuel and manual oil-fuel pre-mixing is not necessary. The oil is contained in a reservoir that connects to a small oil pump in the engine, which needs to be periodically refilled.
  This system is commonly used for motorcycles as it eliminates the need of pre-mixing fuel and two-stroke oil. Vespa is an example where pre-mixing of two-stroke oil is required. Automatic lubrication was introduced for motorcycles by Velocette in 1913.
  An example of application of automatic lubrication system is Suzuki AX100 motorcycle. The motorcycle has a separate oil reservoir on its right side which supplies the cylinder with two-stroke oil proportional to engine speed.

caption: Oil injection pump on a Yamaha DX100- just behind the carburettor (visible on the left)   It is the primary component of two-stroke automatic lubrication system. Amount of two-stroke oil injected by the pump depends on the throttle position. A cable from the throttle is connected to the oil pump indicating throttle's position. A tube ensures flow of oil from the reservoir to the oil pump.
